Perceptions do not rely on light. Even if we are without our eyeballs, we could still perceive things. It makes sense but I think I'm missing something here..

You can only percieve rational, previously percieved, or possible to percieve, phenomina in a dream. For instance, your brain will not create a new color that your eyes, according to the spectrum, can possibly see; everything in a dream is a stream of logged data that, for some reason, is replaying itself. So, that data had to have been taken in from somewhere, processed, in order to be replayed.

That seems to be what she was saying, more or less.

But it will at least be poetic, I suppose...

Hmm... But what if it does end well?
Then I suppose it will be a different sort of poetry, a preferable sort...
A sort I could become accustomed to...

I don't think it was horribly written at all. in fact, it makes perfect sense to me.

I know in the field of Physics, wavelengths of light are often abbreviated to colours. This is done out of convenience, and references how they are usually perceived in everyday life.

However, by the layman's use, as was referenced by the original post, colours are a mental phenomena.

And not surprisingly, this is how my conversations with INTJs usually go. Semantics, them taking things too literally, and me taking things not literally enough. Them never giving the benefit of the doubt, me always giving it etc.

You are right that much of it comes down to semantics. Color, however, is layman's terminology. In the field of physics, more precision is usually desired, and wavelength, frequency, or energy is used. Color is thus synonomous with wavelength, just not nearly as precise.

think about it. dreams and hallucinations both allow you to perceive colour when there is no light. and light doesn't have colour until it hits an optic nerve, just a wavelength.

In a dream, one does not perceive color, one remembers it. Without our eyeballs, we would still perceive many things: sounds, smells, tastes, etc. but not the visual. Asking whether light has color before it is perceived is like asking whether a tree falling in a deserted forest makes any sound. If one considers sound to be the vibration itself, then of course it does; but if one considers sound to be the perception of that vibration, then it does not. Similarly, if one considers color to be an imprecise equivalent of wavelength, then light has that property, whether it is perceived or not.

Now, to confuse matters further: what about the idea of color where there is no light. Is a blue hat blue in a dark room? How about in a room filled with red light? The fabric of the hat still contains pigments that reflect blue and absorb other colors, so in that sense, it is still fair to call it a blue hat, but with no blue photons to be reflected, it will look black.

I like this thinking. I guess it's blue as long as you know that its true nature in white light. However, if you've only ever seen it in red light and it always appears black and you have no knowledge that it's blue, it's a black hat. Its not the absolute truth but perception often stands in for truth.
